By Norman A. Johnson

Norm Johnson has performed a very good activity with a fancy subject, and this booklet is person who might be learn via each scholar of evolution. With a crisp, attractive writing sort, Johnson does an excellent activity illuminating evolutionary subject matters starting from Kimura's impartial concept of molecular evolution to the evolutionary histories of either canines and their proprietors. advanced themes similar to the detection of optimistic choice and the mysteries of genome dimension version are specified by undeniable language that even the main "mathophobic" reader will discover a excitement to behold. Any graduate scholar in biology who's getting ready for a initial oral exam might do good so as to add Darwinian Detectives to their studying checklist, since it is a smart strategy to study the solutions to questions that many professors will ask in such an examination. the former reviewer's comparability to Gould isn't undeserved; Dr. Johnson has the aptitude to rank one of the greats within the subsequent new release of popularizers of technology, a job that turns into an increasing number of vital as technological know-how marches to ever higher heights of advanced discovery.

Example text

The Baby with the Baboon Heart Molecular Evolution Molecular biology provides arguably the most convincing evidence that all known life is related—that is, shares common descent. The most striking feature that demonstrates common descent is the commonality of nucleic acid DNA as the genetic material across all known life. Some viruses (HIV, for example), known as the retroviruses, use the related nucleic acid RNA as their genetic material, but even these retroviruses will convert their RNA information into DNA information at specified times.

The next part of their strategy would then be attempts to sow doubt about Darwinian evolution among an unsuspecting public (especially school boards), presenting ID an alternative. As Forrest and Gross chronicle, the Discovery Institute, through its CSC, has been actively working with school boards in several states (notably Kansas, Ohio, and Washington State). In the case of Kansas, they succeeded in rewriting the standards to place undue doubt regarding what we actually do know about evolution.

DARWINIAN DETECTIVES That we share  of our genes with mice doesn’t mean that humans and mice are  genetically identical; in fact, we are a good deal less than  identical to mice, because each of the gene counterparts we share with them have diverged. In other words, humans and mice have a large proportion of genes arising because humans and mice share a common ancestor, but in the course of time through the action of evolutionary forces, humans and mice now have different variants of the same genes.
